Partlow Gas Controls
Partlow’s self-operating,
throttling gas control valves have been used in a wide variety of
applications for over 60 years. They require no power. They provide
smooth proportional temperature control for a variety of mobile and
stationary applications including air and liquid tank heaters,
ovens, grain dryers, and molten metal operations. All gas controls
utilize the Piston Pak thermal sensing elements.
Most of these Mechanical Recorders
require a Piston Pak sensing element. (some items may contain
mercury)
